yes its normal. my plants do it at night, my outdoors did as well.

not to sure the cause, id think theyd be peak'd up trying to search for light.
maybe someone else knows the exact cause but you should be good :thumbsup:
Gare0440 Reviewed by Gare0440 on . Closet grow - First attempt Good day, fellow growers. I would like to share my first growing experience and some professional feedback and critics would be more than welcome. The 4 plants you can see below came from my dealer who asked me one day if i would like to grow his plants in my closet. As I just moved out of my parent`s house I immediately agreed and transformed my closet into a small grow space. The size of the grow space: 40"wide x 14"deep x 44"high Installed two fans, one for air intake, one for air Rating: 5
